Petroleum and natural gas industries - Drilling fluids - Laboratory testing (ISO 10416:2008)

ISO 10416:2008 provides procedures for the laboratory testing of both drilling-fluid materials and drilling-fluid physical, chemical and performance properties. It is applicable to both water-based and oil-based drilling fluids, as well as the base or “make-up” fluid.
ISO 10416:2008 is not applicable as a detailed manual on drilling fluid control procedures. Recommendations regarding agitation and testing temperature are presented because the agitation history and temperature have a profound effect on drilling fluid properties.

Industries du pétrole et du gaz naturel - Fluides de forage - Essais en laboratoire (ISO 10416:2008)

L'ISO 10416:2008 fournit des modes opératoires pour les essais de laboratoire à la fois en ce qui concerne les matériaux de fluides de forage et les propriétés physiques, chimiques et les performances des fluides de forage. Elle est applicable aux fluides de forage à base d'eau et aux fluides de forage à base d'huile, de même qu'au fluide de base ou au fluide de «constitution».
Elle n'est pas applicable en tant que manuel détaillé relatif aux modes opératoires de contrôle des fluides de forage. Des recommandations en ce qui concerne l'agitation et la température d'essais sont présentées du fait que l'historique de l'agitation et la température ont un effet profond sur les propriétés des fluides de forage.

Industrija za predelavo nafte in zemeljskega plina - Vrtalne tekočine - Laboratorijsko preskušanje (ISO 10416:2008)

Ta mednarodni standard predpisuje postopke za laboratorijsko preskušanje vrtalnih tekočin, tako materialov kot tudi njihovih fizikalnih, kemičnih in proizvodnih lastnosti. Velja za vrtalne tekočine na vodni osnovi in na osnovi olja ter za osnovne ali nadomestne tekočine. Ne uporablja se kot natančen priročnik za kontrolni postopek za vrtalne tekočine. Priporočila glede tresenja in temperature preskušanja so navedena, ker imata potek tresenja in temperatura velik vpliv na lastnosti vrtalnih tekočin.
